CVE-2017-1000158 2 Debian, Python 2 Debian Linux, Python 2024-02-28 7.5 HIGH 9.8 CRITICAL
CPython (aka Python) up to 2.7.13 is vulnerable to an integer overflow in the PyString_DecodeEscape function in stringobject.c, resulting in heap-based buffer overflow (and possible arbitrary code execution)
CVE-2016-3076 1 Python 1 Pillow 2024-02-28 4.3 MEDIUM 5.5 MEDIUM
Heap-based buffer overflow in the j2k_encode_entry function in Pillow 2.5.0 through 3.1.1 allows remote attackers to cause a denial of service (memory corruption) via a crafted Jpeg2000 file.
CVE-2017-5992 1 Python 1 Openpyxl 2024-02-28 5.8 MEDIUM 8.2 HIGH
Openpyxl 2.4.1 resolves external entities by default, which allows remote attackers to conduct XXE attacks via a crafted .xlsx document.
CVE-2016-9015 1 Python 1 Urllib3 2024-02-28 2.6 LOW 3.7 LOW
Versions 1.17 and 1.18 of the Python urllib3 library suffer from a vulnerability that can cause them, in certain configurations, to not correctly validate TLS certificates. This places users of the library with those configurations at risk of man-in-the-middle and information leakage attacks. This vulnerability affects users using versions 1.17 and 1.18 of the urllib3 library, who are using the optional PyOpenSSL support for TLS instead of the regular standard library TLS backend, and who are using OpenSSL 1.1.0 via PyOpenSSL. This is an extremely uncommon configuration, so the security impact of this vulnerability is low.
CVE-2016-6581 1 Python 2 Hpack, Hyper 2024-02-28 7.8 HIGH 7.5 HIGH
A HTTP/2 implementation built using any version of the Python HPACK library between v1.0.0 and v2.2.0 could be targeted for a denial of service attack, specifically a so-called "HPACK Bomb" attack. This attack occurs when an attacker inserts a header field that is exactly the size of the HPACK dynamic header table into the dynamic header table. The attacker can then send a header block that is simply repeated requests to expand that field in the dynamic table. This can lead to a gigantic compression ratio of 4,096 or better, meaning that 16kB of data can decompress to 64MB of data on the target machine.
CVE-2016-6580 1 Python 1 Python Priority Library 2024-02-28 5.0 MEDIUM 7.5 HIGH
A HTTP/2 implementation built using any version of the Python priority library prior to version 1.2.0 could be targeted by a malicious peer by having that peer assign priority information for every possible HTTP/2 stream ID. The priority tree would happily continue to store the priority information for each stream, and would therefore allocate unbounded amounts of memory. Attempting to actually use a tree like this would also cause extremely high CPU usage to maintain the tree.
CVE-2016-0740 2 Debian, Python 2 Debian Linux, Pillow 2024-02-28 4.3 MEDIUM 6.5 MEDIUM
Buffer overflow in the ImagingLibTiffDecode function in libImaging/TiffDecode.c in Pillow before 3.1.1 allows remote attackers to overwrite memory via a crafted TIFF file.
CVE-2016-1000032 1 Python 1 Tgcaptcha2 2024-02-28 5.0 MEDIUM 7.5 HIGH
TGCaptcha2 version 0.3.0 is vulnerable to a replay attack due to a missing nonce allowing attackers to use a single solved CAPTCHA multiple times.
CVE-2016-2533 3 Debian, Python, Python Imaging Project 3 Debian Linux, Pillow, Python Imaging 2024-02-28 4.3 MEDIUM 6.5 MEDIUM
Buffer overflow in the ImagingPcdDecode function in PcdDecode.c in Pillow before 3.1.1 and Python Imaging Library (PIL) 1.1.7 and earlier allows remote attackers to cause a denial of service (crash) via a crafted PhotoCD file.
CVE-2016-3189 2 Bzip, Python 2 Bzip2, Python 2024-02-28 4.3 MEDIUM 6.5 MEDIUM
Use-after-free vulnerability in bzip2recover in bzip2 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted bzip2 file, related to block ends set to before the start of the block.
CVE-2016-2183 6 Cisco, Nodejs, Openssl and 3 more 9 Content Security Management Appliance, Node.js, Openssl and 6 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
CVE-2016-0718 9 Apple, Canonical, Debian and 6 more 14 Mac Os X, Ubuntu Linux, Debian Linux and 11 more 2024-02-28 7.5 HIGH 9.8 CRITICAL
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow.
CVE-2016-5636 1 Python 1 Python 2024-02-28 10.0 HIGH 9.8 CRITICAL
Integer overflow in the get_data function in zipimport.c in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow.
CVE-2016-0772 1 Python 1 Python 2024-02-28 5.8 MEDIUM 6.5 MEDIUM
The smtplib library in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 does not return an error when StartTLS fails, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."
CVE-2016-9189 2 Debian, Python 2 Debian Linux, Pillow 2024-02-28 4.3 MEDIUM 5.5 MEDIUM
Pillow before 3.3.2 allows context-dependent attackers to obtain sensitive information by using the "crafted image file" approach, related to an "Integer Overflow" issue affecting the Image.core.map_buffer in map.c component.
CVE-2013-7440 1 Python 1 Python 2024-02-28 4.3 MEDIUM 5.9 MEDIUM
The ssl.match_hostname function in CPython (aka Python) before 2.7.9 and 3.x before 3.3.3 does not properly handle wildcards in hostnames, which might allow man-in-the-middle attackers to spoof servers via a crafted certificate.
CVE-2015-1283 8 Canonical, Debian, Google and 5 more 13 Ubuntu Linux, Debian Linux, Chrome and 10 more 2024-02-28 6.8 MEDIUM N/A
Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.
CVE-2016-1494 3 Fedoraproject, Opensuse, Python 4 Fedora, Leap, Opensuse and 1 more 2024-02-28 5.0 MEDIUM 5.3 MEDIUM
The verify function in the RSA package for Python (Python-RSA) before 3.3 allows attackers to spoof signatures with a small public exponent via crafted signature padding, aka a BERserk attack.
CVE-2015-5652 2 Microsoft, Python 2 Windows, Python 2024-02-28 7.2 HIGH N/A
Untrusted search path vulnerability in python.exe in Python through 3.5.0 on Windows allows local users to gain privileges via a Trojan horse readline.pyd file in the current working directory. NOTE: the vendor says "It was determined that this is a longtime behavior of Python that cannot really be altered at this point."
CVE-2016-4472 4 Canonical, Libexpat Project, Mcafee and 1 more 4 Ubuntu Linux, Libexpat, Policy Auditor and 1 more 2024-02-28 6.8 MEDIUM 8.1 HIGH
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.
